In the fridge, whole oranges last about 4 to 6 weeks, according to the University of California. On the counter they're at their best for only a few days: in a Serious Eats test, two weeks at room temperature cost oranges 6% of their weight, twice the 3% refrigerated ones lost. Cut oranges keep 1 to 2 days chilled.
The counter is where many oranges sit, and it's the worst place for them after the first few days.
How long oranges last, by where you keep them
| Where | Whole oranges | Cut or sectioned | Source |
|---|---|---|---|
| On the tree | The best storage there is, through the harvest season | n/a | UC IPM |
| Counter | Best eaten within a few days; no official limit | 2 hours, or 1 hour above 90°F | Serious Eats; UC ANR |
| Home fridge | About 4–6 weeks | About 1–2 days, covered | UC IPM; UC ANR |
| Commercial cold storage, 38–48°F | 3–8 weeks, up to 12 in ideal conditions | n/a | UC ANR; USDA Handbook 66 |
| Freezer, 0°F | Don't freeze whole | Sections in syrup: best within 8–12 months | NCHFP |
| Freezer, juice | n/a | Valencia juice: up to 4 months | UC IPM |
No agency we could find publishes a counter time for whole oranges. The counter figure above is a quality judgment drawn from the Serious Eats test.
Why oranges last longer in the fridge
Cold slows respiration, the ongoing activity of a picked fruit that gradually wears down its flavor and texture. An orange doesn't ripen further once it's off the tree, so every day after harvest is a day of decline, and the only question is how fast.
For Serious Eats, editor Genevieve Yam weighed oranges daily for two weeks. The room-temperature fruit lost 6% of its weight and went soft; two of them rotted about halfway through the two weeks. Those that didn't rot looked passable from the outside, but inside the flesh was dried and shriveled. Refrigerated oranges lost 3% and stayed firm. After two weeks they were still sweet and juicy, if a little less tart. Dr. David Obenland, a plant physiologist with the USDA, told her the ideal storage temperature for oranges is about 41°F (5°C), varying by variety.
In a separate bag test in the fridge, oranges in a loosely tied produce bag lost about 1% of their weight against 4% for loose ones, though she couldn't taste the difference. Don't seal the bag shut, since trapped moisture encourages rot. For home storage, UC's orange guide points you to the crisper drawer.
Can the fridge be too cold for citrus?
Over weeks, no; over months, it can be. Citrus is sensitive to chilling, and USDA's Agriculture Handbook 66, the produce trade's storage reference, says California and Arizona oranges may develop chilling injury when held below about 37–41°F. The damage shows up as pitted or stained peel and off flavors, and it invites decay. At 41°F it can take 60 days to appear, or it can surface a day or two after cold fruit comes back to room temperature.
UC's figure for commercial storage of California oranges is 38–48°F. At home, plan on the 4 to 6 weeks UC gives, not the longer trade figures.
Lemons, mandarins and grapefruit keep differently
Lemons are the long keepers. Handbook 66 gives them up to 6 months at 45–54°F in trade storage. A home fridge runs colder, and at 37–41°F lemons usually tolerate 3 to 4 weeks. Chilled too long, a lemon develops pitted skin and loses juice, so a home fridge suits about a month's supply. Mandarins are the short keepers, stored commercially at 41–46°F for up to 4 weeks, with chilling injury possible below 41°F. Grapefruit hold quality for up to 6 weeks in commercial cold storage, by the same handbook, and pit if chilled to 41°F or below. The thin-skinned Meyer lemon is the exception: UC Riverside's Improved Meyer entry quotes an old verdict that it's too tender and juicy to stand up to storage, so buy it close to when you'll use it.
Leave oranges on the tree if you grow them
UC's home-garden guidance says ripe oranges keep best on the tree, and Handbook 66 agrees that in normal weather they store better there than in cold storage, so pick as you need them through the season.
The exceptions are frost and damage. UC ANR says temperatures below 28°F can freeze the fruit, so pick ahead of a hard freeze. A fruit snapped off by hand can tear at the stem, and a torn or scraped peel spoils sooner, so use those first. Clipping the stem avoids that; our post on citrus picking tools covers the clippers we like.
How long do cut oranges last?
About 1 to 2 days, covered, in the fridge. Cut fruit left at room temperature more than 2 hours (1 hour above 90°F/32°C) should be thrown out, fruit salad included, according to UC ANR.
For longer, freeze the sections. The National Center for Home Food Preservation says to peel the fruit, remove all membranes and seeds, pack the sections in containers and cover them with cold 40% syrup. Its general guidance gives frozen fruit 8 to 12 months at 0°F for best quality. Leave navels out of it. UC ANR explains that frozen oranges turn bitter from limonin, and navels contain the most.
Signs an orange is past it
Mold settles it. Handbook 66's advice for lemons, to remove any moldy fruit at once so it can't spread, suits any fruit bowl, and the same handbook notes that decay moves quickly once oranges leave cold storage. Check the bowl every few days.
The harder case is the orange that looks fine. In the Serious Eats test, two-week-old counter oranges passed for fresh until they were cut. Firmness is a better guide than looks: When buying, UC ANR says to choose firm oranges that feel weighty for their size and have no soft spots.
When a bag of oranges is more than a household can eat in a month, marmalade is the old answer; our marmalade collection holds every variety we make, and the citrus collection shows which fruit goes into which jar.
